Abstract
This work presents an experimental and theoretical
study on the improvements to pulsed diode laser
gain-switched (GS) optical sources. Simultaneous
compression and reshaping of the limited quality pulses
obtained with this technique are reported using a highly
nonlinear optical loop mirror (HNOLM) directly coupled
to the diode laser source, without any previous pulse
conditioning. The HNOLM is based on the use of a
microstructured optical fiber and a highly nonlinear
semiconductor optical amplifier; it is compact and
offers benefits in terms of reduced system complexity.
The experimental observations are compared to a
theoretical model of the system, and excellent agreement
is observed.
